OBJECTIVE To examine whether adolescent flexibility, endurance strength, and physical activity can predict the later occurrence of recurrent low back pain, tension neck, or knee injury. METHODS In 1976, 520 men and 605 women participated in a sit and reach test (flexibility) and a 30 second sit up test (endurance strength). In 1976 and 2001 (aged 37 and 42 years) they completed a questionnair...

This study of associations of sports participation with perceived and actual physical fitness, and total physical activity for 525 10- to 17-yr.-old boys and girls in groups of 10-11-yr. (56 boys and 64 girls), 12-13-yr. (68 boys and 68 girls), 14-15-yr. (70 boys and 71 girls), and 16-17-yr. (68 boys and 60 girls) was based on the Physical Activity Index derived from a questionnaire by Telama, ...

AIMS To compare the effects of endurance training with endurance strength training on the anthropometric, body composition, physical capacity, and circulatory parameters in obese women. METHODS 44 women with abdominal obesity were randomized into groups A and B, and asked to perform endurance (A) and endurance strength training (B) for 3 months, 3 times/week, for 60 min. Dual-energy X-ray abs...

Increment of lipoprotein(a) [LP(a)] Concentration, as a coronary artery disease risk factor. Probably LP(a) not been affected by physical activity and it is resistant against exercise stimulation. The aim of this cross-sectional study was to determine and compare of LP(a) concentration in selected groups. This analytical study was designed in three groups of subjects (15-25 yrs) who were volunt...

[Purpose] The purpose of this research was to investigate the physical condition of middle-aged workers in Korea by gender. [Subjects] In total, 2,644 middle-aged workers (male, n = 2,175; female, n =469) ≥50 years of age from eight geographical areas were evaluated from 2007 to 2008. [Methods] The subjects' physical condition, muscular endurance, reaction, flexibility, agility and age of physi...

BACKGROUND Patients with COPD may experience respiratory muscle weakness. Two therapeutic approaches to the respiratory muscles are inspiratory muscle training and calisthenics-and-breathing exercises. The aims of the study are to compare the effects of inspiratory muscle training and calisthenics-and-breathing exercises associated with physical training in subjects with COPD as an additional b...

The aims of this study were to investigate whether the impairment in endurance of limb muscles is a general finding in chronic obstructive pulmonary disease (COPD) patients, affecting even those with mild-to-moderate disease or relatively normal physical activity. In addition, this study aimed to determine the physiopathology of exhaustion in local endurance tests and whether the reduction in q...
